Book excerpt: This is the 15th report, prepared by a team of independent experts, which explores major development issues of global concern. The 2004 report focuses on issues of cultural liberty and concludes that countries must actively devise multicultural policies to prevent cultural discrimination (whether on grounds of religion, ethnicity or language), since the expansion of cultural freedoms is at the core of human development. Rather than presenting a threat to state unity, the report argues that diversity is the only sustainable option to promote stability and democracy within and across societies. Issues discussed include: confronting extremist movements for cultural domination; myths surrounding cultural liberty and development; the impact of globalisation on cultural choice; social exclusion, human rights and participation. It also includes data tables for the Human Development Index (HDI) which measures key social and economic indicators for rich and poor countries, including life-expectancy, health and sanitation, employment rights, gender equality, education and income per-person.
